Why do tomato leaves on the plant curl?
Tomato leaf curl is usually due to over watering and or poor drainage. There is a disease call yellow leaf curl caused by a virus, but most people who ask this question have green leaves that twist or curl over on themselves. The cure is to make sure that you’re watering evenly. I’ve noticed that many people water their toms WAY too much. Evenly moist is where you want to be.
